So there i have two classes.
The main class, SleepyHollow, creates the main frame and the menu.
Inside the SleepyHollow class, i create an instance to NoteBook class
and call on it.
The NoteBook class creates a notebook and adds tabs to the notebook.
However, inside the NoteBook class, i try to call a SleepyHollow method
(the 'popup' method, for displaying dialogues), but i keep getting this
error:
/usr/bin/python -u "path/to/file/file.py"
